htree questions
I decided that I would try out 2.5.44, and I noticed that htree was merged. If I don''t do the tune2fs -O dir_index, and e2fsck -D, the (exisintg) fs won''t use htree, right? Once I do the tune2fs and e2fsck, will I still be able to go back to a non-htree kernel if needed? (Will a htree-ized fs work on a non-htree kernel?) I''m guess...

e2fsck too old / ext3 HTREE errors
...----- 612 files ### fs was modified? what''s going on here? ### a 3rd run gives: root@sheep:/# /usr/local/sbin/fsck.ext3 -fv /dev/sda8 e2fsck 1.30-WIP (30-Sep-2002) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Problem in HTREE directory inode 16430: node (0) has bad limit (31744) Clear HTree index<y>? ### well, and these HTREE issues are continuing (sp?) to infinity. that means, in *every* fs-check there are always HTREE issues, and i don''t know if i should fix these by typing "y" or so. what...

2.4.20 & htree
Apologies for the newbie question: I have a (stock) 2.4.20 build (*not* -ac), and I''m trying to work with large ext3 directories. By large, I mean 160,000 files per directory. (Yes, I know it would be better in nested directories but such is life). I feel htree would benefit me. Having upgraded from an earlier version of 2.4, I don''t see any change, and close reading of the 2.4 changelog suggests that htree isn''t in there - only a patch to prevent non-htree builds reporting corruption after being written to by an htree build. Did I read...

ext3 2.4.21 htree tests
...N/A, 1078 Remove : 611, N/A, 1310 Ok so results are not that great - better to use more directories. Files spread over 1000 directories: Create: 409, 305, 284 Remove: 138, 96, 141 Create: 377, 312, 276 Overwrite: 317, 246, 268 Overwrite2: 321, 241, 265 I was interested in seeing if the htree patches would give me a performance increase - although I guess the sequential nature of the file creation/deletion probably will not benefit - although I was suprised that adding dir_index hit the overwrite and removal speed - probably based on this testing I won''t use this feature (y...

htree and nfs benchmarks
Well here is what I got from testing htree with NFS. http://labs.zianet.com/benchmarks_html/postmark_benchmarks_NFS_100_htree.html It looks like htree improves performance when the storage device is local(as per my previous post) but it looks like htree degrades performance when used in conjunction with NFS. I am going...

New htree patches?
Hello, Could someone create some newer htree patches for the 2.4.x kernel? There are some bug fixes in the 2.4.21-rc releases that would be nice to have but the htree patches preceed those and they won''t apply cleanly to later pre/rc kernels. It sounds like Marcelo may be about ready to put out 2.4.21 so it may just be worth ho...

htree stabilitity and performance issues
Guys, I have recently applied the latest 2.4 htree patch on a heavily loaded nfs server. The nfs server serves around four very busy clients that deliver email in maildir format and pop3/imap clients. Being maildir I presumed that the htree patch would improve performance - but I was wrong. Load on the server went up by around 25-40%. After...

htree and Severn
My reading of the kernel.src.rpm doesn''t indicate that Severn has ext3 htree patches. Stephen, were there any issues seen during Cerberus testing ? Regards, Yusuf -- Yusuf Goolamabbas yusufg@outblaze.com

ext2->ext3 empty file creation
...o ext3. the partitions are nearly empty. I ran a program to create empty files, having names in lexicographical order. The time taken to create empty files (100 .. 100000) is same on an ext2 partition and a ext3 partition. Can anyone pls. tell me why there is no difference in the time taken. Is the htree algo. implemented in both ext2/ext3 of 2.4.7-10 thanx in advance. -Sagar some info of the m/c: redhat linux, 2.4.7-10, 512MB RAM, nearly empty partitions.

Updated 2.4 htree patches available for 2.4.21rc5
I''ve backported all of the bugfixes to the 2.5 dxdir/htree patches to 2.4, and have created a new set of patches for Linux 2.4.21rc5. At this point it *looks* like we''ve fixed all of the htree bugs that people have reported, including the brelse bug, the memory leak bugs, and the NFS compatibility problems. I''ve done *very* light testin...

Ext3 indexed directory extension.
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Searching in the ext3 filesystem mailing list I have seen that there is an indexed directory extension for it. Is this extension stable code ? Has anyone test it ? How may I obtain and install it ? Is it available in any of the last kernel releases ? Greetings. - --- Carles Xavier Munyoz Baldó carles@descom.es Descom Consulting Telf: +34

FS-corruption on ext3 with HTrees
Hi, I''m working with Prof. Zadok on versionfs, a stackable versioning file system. I face some problems with the unlink operation on ext3 with htree. On an unlink, I make a copy of the file (version/backup) and unlink the original file. But some files that have been unlinked are "linked back" to another file. For example, on deleting the file ''foo'', the file itself is deleted and its backup is made, but "f...

ext3 htree upgrade
Hi Guys, I am planning on upgrading an existing NFS exported filesystem to the ext3 htree patch on kernel v2.4.23. Will the patch index directories automatically after tune2fs -O dir_index or should I do an e2fsck -Dfy on the filesystem before remounting?

performance issue with overwritten files
Hi Guys, I have experienced a recent performance issue with an ext2 filesystem. Essentially I have had several files that get overwritten on average once per day. This has been happening for about a hear when the program accessing and reading those files started from several milliseconds to 15-20 seconds to open and read the file. Moving the directory to a new name and copying the contents

FS corruption; HTREE-related?
Over the last two days we''ve been seeing a fair bit of this: ---- # ls -laR > /dev/null ... ls: ./server2/b/user/bxyz/392.: Input/output error ---- This is with the latest htree patches applied to 2.4.19, and latest e2fsprogs-test, on a dual AMD system, with 5x73GB SCSI drives on a MegaRAID controller. We''re using the gcc 2.96 that comes with RH7.3. esfsck shows "Inodes that were part of a corrupted orphan linked list found." We''ve been hittin...

What happens with the indexed directory patch ?
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I''m trying to install the htree indexed directory patch to my RedHat kernel-source-2.4.18-10, but it seems that doesn''t go. First I tried the ext3 patch (I have sent some emails to this list telling the problems I had with it). Now I have just test the ext2 patch. I get it from: http://people.nl.linux.org/...

htree and nfs
Hi Guys, I am quite keen to try out the new htree extensions to ext3 however I wish to use them under NFS. I have noticed comments from the developers saying that it doesn''t work properly under NFS. What exactly is the current status of the issue?
